Abstract

An antenna switching system includes a first antenna, a second antenna, a first sensing unit, a second sensing unit, a controlling unit, and a switching unit. The first sensing unit detects a distance between an object and the first antenna. The second sensing unit detects a distance between the object and the second antenna. The controlling unit is electronically connected to the first sensing unit and the second sensing unit. The switching unit is electronically connected to the controlling unit, the first antenna, and the second antenna. The controlling unit is configured to activate and deactivate the first antenna and the second antenna via the switching unit based on detections of the first sensing unit and the second sensing unit.

Description

technical field [0001] The invention relates to an antenna switching system and a wireless communication device using the antenna switching system. Background technique [0002] As one of the key components of wireless communication devices, antennas occupy an extremely important position in the design of wireless communication products. Since the position of the antenna in the wireless communication device is usually fixed, the radiation efficiency of the antenna is often affected by hand grips, thus affecting the communication quality. Especially with the addition of the LTE (Long Term Evolution, Long Term Evolution) frequency band, high-bandwidth antennas have become an essential component of wireless communication devices. issues to consider in design. Contents of the invention [0003] In view of the above circumstances, it is necessary to provide an antenna switching system that avoids the influence of hand-holding. [0004] In addition, it is also necessary to pr...
